Definitions
- the general object of this invention has been to provide a refractory composition whichshall be elastic and very durable, thus preventing cracking, disintegrating, corrodmg, and oxidizing.
- Another object has been to provide a refractory composition which shall be-easily and cheaply manufactured and one in which, in order to permanently bind the constituent materials together, it shall be unnecessary to raise the composition to the temperature of recrystallization.
- Another object has been to provide a composition which shall resist chemical action and one which shall greatly increase the life of the articles which are made therefrom.
- this composition is described as applied to the construction of a crucible; it being obvious that it can be used for making any heat resisting articles; such as, fire bricks, retorts, muflies, refractories, furnace cores, tubes, combustion boats, fur nace linings, and heat resisting cements.
- Binder substantiall 7 parts.
- substantially e ual parts of silicon carbide, crystalline alumina, and silicon oxide are set forth, it being understood, however, that these elements are the equivalent of each other and that the total, 68 parts, of the entire composition may be divided between these three elements in 70 any desired manner.
- fire sand is not a chemically inert refractory electric furnace product, and, therefore, it is not considered to be the equivalent of the silicon carbide, crystalline alu- 7 mina, or silicon oxide.
- clay may be used, or if desired, a carbonizing binder (such as tar, pitch or molasses) may be used as a binding agent.
- a carbonizing binder such as tar, pitch or molasses
- a fusion mixture is preferably used for protecting the composition against oxidation and disintegration.
- a clay having a low fusion point, may be used as such fusion agent.
- I may substitute a metallic ornon-metallic salt (such as borax or feldspar), oxide (such as oxide of iron) or other suitable fusion mixture. It will be understood “that a combination of different salts or different oxides, or a combination of both of these fusion agents may be used. It is necessary, however, when carbonizing binders are used, to increase the percentage of such binders.
- the ingredients are thoroughly mixed and placed upon a potters wheel, where the crucible is spun in the usual manner, or, if desired, the mass may be pressed or molded into shape. After the crucible is formed by spinning, pressing or molding, it is dried and then baked at a low temperature (approximately .100 0 C.) After baking the crucible is ready for use.
- silicon carbide, crystalline alumina, and silicon oxide are each a product of the electric furnace, and are, respectively, chemical compounds of silicon and carbon, aluminum and oxygen, and silicon and oxygen.
- Each of these materials has a very high fusion point; is very inert chemically, as is graphite; is a good conductor of heat; has an extremely low coefficient of expansion; and shows practically no oxidation under extreme heat. 1
